Bug Type: Feature/Change Request
PHP Version: 5.3.2RC1
New Comment:
I second this feature request.
Function Array Dereferencing allows programmers to write cleaner code
and is adopted by many other programming languages such as Ruby and
Python. Adding this feature doesn't break any previous code written
in PHP.
Examples:
============
With FAD:
----
$var = func()[2];
Without FAD: (Current PHP)
----
$var = func();
$var = $var[2];
OR
$var = func();
$othervar = $var[2];
unset($var);
With FAD:
----
otherfunc(func()[2]);
Without FAD:
----
$var = func();
otherfunc($var[2]);
unset($var);

Description:
------------
In Perl, I am able to do something like:
print (explode(",", $myString))[1];
which would print the second result of explode (which returns an
array). Sadly, this feature is lacking in PHP. I'd really like to see
this in PHP, because it adds so much convenience to coding, and
shortens it, rather than having to assign to a variable, then obtaining
the value from the variable.
Reproduce code:
---------------
<?php
$myString = "The,quick,brown,fox";
$secondpart = (explode(",", $myString))[1];
echo $secondpart;
?>
Expected result:
----------------
quick
Actual result:
--------------
Parse error: syntax error, unexpected '[' in
/home/billy/Desktop/index.php on line 3
